SU114136A1 - Turbodoloto for well drilling - Google Patents

Description

For drilling, we obtained 11) replacement of the turbo hammer, in which the turbine shaft is provided with a friction rim to interact with the outer surface of the rear cones of the bit cutters.

The turbodol offered is more compact compared to the known similar turbodol. This is achieved by the fact that a planetary gearbox is installed in his KOjinyce), the satellites of which transmit vrash, the spindle moment.

The drawing shows two sections of the proposed turbodolder.

The shaft of the turbo-chute / with the help of a split-head (or by a fixture) coupling 2 transfers a twisting moment njTOKy 3. A hydraulic load acting on the turbine is transmitted through the same coupling. Stock Uni into thrust ball bearing 4, which is used on roller cone 5 bits 6. On the rod 3 there is a gear crown 7 of the planetary gear, coupled to satellites 8, which engage with the inner three crown 9. Satellites 6 transmit B1 ) The torque to the spindle / (9, with which the bit body 6- Spindle is connected. The JG rotates in the upper thrust bearing 11 and lower) to the spinal spindle 12. The thrust ball bearing installed above the ball ends of the bit also transmits the hydraulic load to the turbine.

In rez.; 1t; Those constructions of the |,) UKP1P-1 turbo-drill are provided with a separate load on HjaponiKn, which significantly increases their durability.

Subject invention

Turbodolite for drilling wells, the turbine shaft of which is equipped with a friction crown e.1 interacting with the outer surface of the rear cones of the HiajiorucK chisel, from l and hp; e e with the fact that, for the purpose of compactness, in the case of his wetter a planetary gearbox , whose satellites are crowding the spindle moment which is disturbing.
